• VM load and ping problems after replacing server motherboard

  - by Andre

  Recently, we had to replace the motherboard of one of our servers. The procedure was done by IBM as it had guarantee. The server runs ESXi 5.1, with several virtual machines, including our main mail server (Domino) and a file server. After the replacing the motherboard and staring the VMs, ESXi asked us if we had moved it or copied (different motherboard is like a different computer). We clicked the latter. We started each machine and after some basic reconfiguration, all of them were up. However, we have been having problems with the mail server, it has been acting really slow at times (this could be when it syncs with the secondary mail server) and we have been checking with Centreon (a Nagios frontend) that its CPU load has been a bit high at times and ping response too. There was a moment this morning in which I tried connecting via SSH console and it was really slow to show login and basic commands like ifconfig and top. This particular mail server is a CentOS 4.4.7 64-bit. The little configuring we had to do after restarting it was to configure the network connection as it was resolving through DHCP. Our mail software is Lotus Notes server 9. Do you know of any way in which this replacement may be causing these difficulties, and how to fix it? Thanks.

• Laptop seemingly randomly "freezes" to the point of no longer executing applications

  - by Aierou

  After upgrading to Windows 8 pro on my Samsung Series 7 Chronos NP700Z5C-S04US (may be relevant, I'm not sure), my computer began to stop allowing the execution of any service or application, as well as discontinuing the update of the clock until a hard shutdown was performed. This seems to occur randomly after periods of inactivity and I've no idea the cause. These are measures I have already taken in order to attempt to stop this: -Obviously Googling potential answers to this problem -Updating all drivers -Researching all events that have occurred around the time of the failure to respond (with no results) -I tried applying "bcdedit /set disabledynamictick no" which was a hotfix for what seemed to be the same error but was not. Here is some more, potentially related, information about the error: -No BSOD (actually, I haven't at all experienced a BSOD with Windows 8) -Computer seems to have a problem shutting down/restarting most of the time (Hangs at the point where it should completely turn off) -New sound instances are not able to play, but previously loaded containers function properly -As mentioned before, the clock freezes at the time of the error -USB devices function properly -Servers that I was running fail to respond on my end, but stay online. If you require more information, please request it specifically and I will be happy to oblige. Thanks.

• Windows 8 install app for multiple user accounts

  - by Robert Graves

  I purchased Adera episode 2 intending to play through it with my son. We each have our own user account on the same PC. When my son logged in, he was prompted to purchase the app which I had already purchased, installed, and played on the same PC. So I checked the Terms of Use. After selecting an app in the store, there is a Terms of Use link on the left side under the Install button. It is almost impossible to identify it as a link unless you put your mouse over it. The Terms of Use are standard across all apps in the store, not specific to particular apps. The terms of use indicates that the app may be installed on up to five devices, but says nothing about multiple user accounts on those devices. However, this Microsoft blog article indicates that it is allowed. Say, for example, that your family has a shared PC. You have previously used your Microsoft account to purchase a game that all your kids like to play. You can install it for each of your kids by having each of them sign in to their Windows accounts on the shared PC, then launch the Store and sign in to the Store using your own Microsoft account. There, you’ll see all your apps and you can re-install the app on your kid’s Windows account. Installing apps on multiple user accounts on a shared PC still only counts as one of the five allowable PCs where you can install apps. So I have two questions: Is it permissible under the Terms of Use to install the app under multiple accounts on the same device? If so, how do I do so given that my son has already signed into the store using his own Microsoft account.

• Can't delete ntuser.dat file to remove profiles after reboot

  - by Matrix Mole

  I've ran into an issue where some servers will not release the handle on the ntuser.dat file even after a reboot. Or quite possible, after the reboot, the ntuser.dat file is getting re-loaded into memory. The user accounts are definitely not being accessed (some of them belong to users that have not been with the company in over a year). It seems to be on Windows 2003 servers, but I can't be 100% certain that there aren't some 2000 servers showing this issue as well. When I try to use process explorer or handle.exe from sysinternals to kill the handle on these ntuser.dat files, the handle remains open and connected. Handle.exe even reports that the handle was broken while it remains in use. I've even taken ownership on the file and tried to kill the handle to no effect (windows shows I have ownership of the file, but still refuses to release the handle). I have looked into the registry to see if I can discover where the files may be getting loaded at. Unfortunately, the username is appearing in too many places for me to be certain which one is actually loading their reg file into memory. Any suggestions on how I can either break the handle on the files, or prevent them from getting re-loaded after a reboot?

• Read non-blocking from multiple fifos in parallel

  - by Ole Tange

  I sometimes sit with a bunch of output fifos from programs that run in parallel. I would like to merge these fifos. The naïve solution is: cat fifo* > output But this requires the first fifo to complete before reading the first byte from the second fifo, and this will block the parallel running programs. Another way is: (cat fifo1 & cat fifo2 & ... ) > output But this may mix the output thus getting half-lines in output. When reading from multiple fifos, there must be some rules for merging the files. Typically doing it on a line by line basis is enough for me, so I am looking for something that does: parallel_non_blocking_cat fifo* > output which will read from all fifos in parallel and merge the output on with a full line at a time. I can see it is not hard to write that program. All you need to do is: open all fifos do a blocking select on all of them read nonblocking from the fifo which has data into the buffer for that fifo if the buffer contains a full line (or record) then print out the line if all fifos are closed/eof: exit goto 2 So my question is not: can it be done? My question is: Is it done already and can I just install a tool that does this?

• Cisco IOS ACL: Don't permit incoming connections just because they are from port 80

  - by cjavapro

  I am going much based on my memory and I may not be correct on all of this. On a Cisco 851 (IOS) that uses a BVI or a bridge-route (the servers on the inside are configured with static and public IP addresses). I would apply two access lists (both end with deny ip any any log) on FastEthernet4 (the WAN port). There would be one for FA4 in and another for FA4 out. FA4 out would have a line like access-list 110 permit 98.76.54.0 0.0.0.255 gt 1023 any eq http I think this means from 98.76.54.* with a from port of at least 1024 can connect to any other machine with a destination port 80. So, then I have to allow the response to the HTTP connection. FA4 in would have a line like access-list 120 permit any eq http 98.76.54.0 0.0.0.255 gt 1023 Now the problem with that is that anybody on the outside can set their from port to port 80 and then connect to any inside port that is at least 1024. How do we prevent this and require the incoming data to be a response to the outgoing data.

• Any ideas why Ettercap filters aren't seeing packet data?

  - by Bryan

  I'm using an Ettercap filter to detect a query response coming back from a particular service on a remote machine. When I see a response from the service, I'm searching through the data in the packet to see if an offset is a specific value, and if so I'm changing the value at another offset. Trouble is, when I try this on a new virtual machine I built my Ettercap filter's no longer getting any data in the DATA.data variable available to it. if(ip.proto == TCP && tcp.src == 17867) { msg("Response seen!\n"); if(DATA.data + 2 == "\0x01") { msg("Flag detected!\n"); DATA.data + 5 = 0x09; } } The filter's getting applied to the traffic because "Response seen!" messages get printed out by Ettercap. However, "Flag detected!" messages do not. I think DATA.data is indeed empty because if I change my second "if" statement to check for DATA.data == "" then the "Flag detected!" message gets printed. Any ideas why this may be happening?! Also, if this is the wrong site to be asking questions like this, please let me know. I wasn't sure if it fit better here or somewhere like superuser or serverfault. By the way, this is a cross-post from StackOverflow... I should have posted on this forum instead I think. :)

• ssh hangs on "Last login" line

  - by Pavel H

  This happened for the first time three days ago - I ssh to the server, authenticate using a password, get the welcome message but it remains hanging on the "Last login:..." line. The command line doesn't show and the server doesn't react to my input. Other services on the server keep working ok (apache, tomcat, database, ..). The box has an out-of-band management using which I was able to restart it. After the restart the ssh worked ok again and I didn't find anything suspicious in the logs. Three days later the same problem occurs on this box again, and newly on yet another server in the cluster - 100% same symptoms. Both servers have about 2 month old installation of Debian Squeeze (6.0.2) and the problem never occurred before despite frequent ssh-ing, so it should not be a problem of settings. We haven't been installing anything new for quite some time now. I also made sure there is enough disk space on both servers. Since it started to happen all of a sudden on two servers at about the same time, I suspect some bug may have been introduced via Debian updates, yet I haven't been able to find anyone with the same problem. Most similar issues I have found: ssh freezes at the "Last Login Line" - in our case everything worked fine until recently, so nothing related to settings should be our problem. Diskspace checked, I couldn't check the memory but I would expect something would be in the logs if the system had been running out of it. Remote Fedora system unresponsive, odd but consistent behavior when trying to log in - problem with high load on the server; unlike in this case, nothing changes even if I wait for 10+ minutes

• Cannot install windows. Compaq Presario CQ62

  - by Matthew

  I bought a used Compaq Presario CQ62 for cheap, and went to install windows on it. I formatted the partition and went to install when I got this error.... Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available and restart the installation. Error code: 0x80070017 I have used this disk before with no problems, but internet searching suggested I burn one at 2x speed because that helps for some reason... I'm burning one now, but my question is, why would I get this error, OTHER than the disc being bad? I'm pretty certain this one isn't as I have used it before... (ok so the slowly burned cd (using imgburn) didn't work either so it's DEFINITELY not the disc) Thanks in advanced for any answers Also I took one stick of ram out because internet searching also suggested that, but it didn't make a difference. Also I ran memory and hard drive checks and they passed fine. Also I reset the motherboard options to default What could it be!? Help I'm completely stumped...

• Mail-Merge on Steroids: Can Word 2003 do this?

  - by richardtallent

  I have a huge report to put together, made up of over 1,000 smaller, nearly-identical reports. Each report includes: General 1:1 information (basic mail-merge stuff) Lots of text, some of which may need to be disabled or have alternate text based on a boolean field. A few embedded images, preferably loaded via HTTP URL, but if they have to be on the a file system thing I can do that. (Filenames will be provided as a field in the data source.) Fortunately, all images are roughly the same size/shape. Several 1:m tables with a few fields apiece. The kicker is the master/child tables. I've seen examples for Word 2000 for doing this by left-joining the master and child table and using some IF/THEN logic to know whether to jump to the next master record. But in my case, I have several of these subtables, so that approach won't really work. So, can Word 2003 handle arbitrary master/child tables? If so, how? If not, I considered InfoPath, but I haven't used it before, and it seems to be made for data entry, not long formatted reports. I'm a software developer, so I could always hack something together with a massive VBA macro, or generating the report in HTML on the web server (where the data is coming from anyway). But I'm hoping Word will work without such gymnastics, since it will give the ultimate users of the report template better control over formatting and making minor changes.

• Triple-Boot + 4 partition Limit

  - by dsimcha

  I just bought a new hard drive so that I could convert my XP-only machine into an XP-Ubuntu-Windows 7 triple boot machine. Since the drive is absurdly huge (1 TB) I wouldn't mind throwing ReactOS into the mix, too. I just found out that master boot records are limited to 4 entries, meaning 4 primary partitions. I had Windows XP set up on my old drive as a boot partition, a program files partition and a media partition. Since I really didn't want to install XP from scratch, I cloned this setup on my new drive. This leaves me one MBR partition entry for installing Windows 7, Ubuntu and ReactOS. I'd like to avoid having to install XP from scratch like the plague, partly because it's supposed to be a safety net in case things go wrong with my other OS's and because I've invested a lot of time getting it set up exactly the way I like it. Here are the options I've considered and why I don't like them: Install Windows 7 on my media partition. This would work, but I prefer to keep my media partition completely separate from any OS, so that I can reformat an OS partition without affecting my media partition at all. Use wubi or something to install Ubuntu in the same partition as something else. Again, this is brittle. Move all my media to a logical drive on an extended partition. Create another logical drive on this extended partition for Ubuntu. The problem here is that extended partitions are rather brittle--if you nuke one, it renders the rest useless. Just put the old drive back in my computer and run XP off it. Use the new one for the other OS's. The problem here is that the old drive is slower and uses extra power, generates extra heat, etc. Can anyone suggest any other possibilities that I may have overlooked?

• tomcat vs FULL J2EE Solutions

  - by jrhickey

  We are getting ready to make a major revision in our Web Application architecture which currently is running on JBoss 4.2. At first we were looking at moving from 4.2 to JBoss 6 but after some research tomcat may be a better solution for us. My first question is their anything that JBoss can do that tomcat cannot do assuming you are using the correct plugins. We do not really use EJB's in our solution and it would appear there are simple plugins for web services, JMX and other features. Tomcat appears to have much better support, faster upgrade cycles and many, many books. Since there is less to the system it also seems much easier to support from an admin point of view. What am I missing? The main features we want to enable are better clustering support and session replication / persistence. We will consider other application servers as well such as Glassfish / Geronimo. quote form a web article: Apache Tomcat is the world’s most widely used web application server, with over one million downloads per month and over 70% penetration in the enterprise datacenter. Tomcat is used to power everything from simple one server sites to large enterprise networks.

• Certificates in SQL Server 2008

  - by Brandi

  I need to implement SSL for transmissions between my application and Sql Server 2008. I am using Windows 7, Sql Server 2008, Sql Server Management Studio, and my application is written in c#. I was trying to follow the MSDN page on creating certificates and this under 'Encrpyt for a specific client', but I got hopelessly confused. I need some baby steps to get further down the road to implementing encryption successfully. First, I don't understand MMC. I see a lot of certificates in there... are these certificates that I should be using for my own encryption or are these being used for things that already exist? Another thing, I assume all these certificates are files are located on my local computer, so why is there a folder called 'Personal'? Second, to avoid the above issue, I did a little experiment with a self-signed assembly. As shown in the MSDN link above, I used SQL executed in SSMS to create a self-signed certificate. Then I used the following connection string to connect: Data Source=myServer;Initial Catalog=myDatabase;User ID=myUser;Password=myPassword;Encrypt=True;TrustServerCertificate=True It connected, worked. Then I deleted the certificate I'd just created and it still worked. Obviously it was never doing anything, but why not? How would I tell if it's actually "working"? I think I may be missing an intermediate step of (somehow?) getting the file off of SSMS and onto the client? I don't know what I'm doing in the least bit, so any help, advice, comments, references you can give me are much appreciated. Thank you in advance. :)

• Determining physical location of data on a disc

  - by Synetech

  Does anybody know of a way to find out where, physically on a CD or DVD a given piece of data would be located? I am trying to watch a DVD at the moment, and am about half-way through, but it keeps dying at a specific spot in the film, presumably because of a scratch. I have a repair kit, but I don’t know where to focus my repair because there are several scuffs and scratches on the disc and I have no way of knowing which one is causing the issue. Obviously, cleaning all of them is inadvisable because not only does it waste the consumable materials in the kit, but not all of them are a problem, and by working them, some may become unreadable. Moreover, just because I am half-way through the movie does not mean that it would be half-way from the hub to the edge for several reasons: Discs have more data towards the outer edge than the inner edge (circles are more mathematically complicated than rectangles) The disc is not completely filled up (and even if it were, the movie itself would be be using it all, there are extras and such) Because in this particular case it is a commercial DVD, it is also dual-layer which further complicates manual determination As such, I am trying to find a program that can let me identify a file (or part thereof), cluster, etc. and show me a picture of where on the CD/DVD it would be located. That way, I can look at the disc and fix any scratches that correspond to that distance from the hub. For example, the image below might indicate where on a disc a couple of files or range of clusters would be located, so by looking for anomalies in those areas (rotating as necessary), the correct one can be identified. I’m sure it can be done since at least one form of copy protection (DPM) uses it and DVD-lab Pro includes a “DVD Topology” feature to do this.

• Are email addresses mandatory for Windows 8 login names?

  - by Cedric Martin

  I've got a computer running Windows 8 and in the user accounts I can see four accounts (they're in french, here's a rough translation): [email protected] / administrator Veronique YYY / [email protected] ASP.NET Machine Account / local account guest account / the guest account is desactivated I've got several questions but they're all related to email addresses and login names / accounts. Are email addresses mandatory for Windows 8 login names? Can you mix live and non-live user accounts on a Windows 8 system? Is it possible to have a live Windows 8 user account which is not using a @live.xx email address? Is it possible to have a non-live Windows 8 user account which is using a @live.xx email address? If the gmail.com email address of the admin is not a live Windows 8 account, does this mean I can create a "fake" email and use that as the email of a new Windows 8 account? Basically I don't understand very well why there are email addresses displayed on the login screen and why there are both @live.xx and @gmail.com email addresses on the same system and answer to the questions I asked above may help me understand a bit better what is going on (I'm coming from a Linux / OS X background. I literally haven't used Windows in more than a decade).

• What can be a reason for phpMyAdmin login to be not working (not at all, no reaction on submit)?

  - by Ivan

  When I open "http://localhost/phpmyadmin/", enter "root" as the user name and my MySQL root password and press go, then if I was using Firefox, I was getting offered to download index.php file (of a zero length), if I was using Opera 11, it said "Connection closed by remote server". Following recommendations I've removed all packages related to phpMyAdmin, PHP, MySQL and Apache and then reinstalled them step-by step (instead of just issuing apt-get install phpmyadmin and relying on the system to install the whole LAMP stack via dependencies as I've done before). The only change I've got was Firefox to stop offering to download index.php - now when I press Ok to submit my password, it just doesn't show any visible reaction at all. What may the reason be and how to fix it? I use up-to-date Xubuntu 11.04. Reinstalling the whole LAMP stack and phpMyAdmin did not help, neither did removing AppArmor. I've tried to use SQLBuddy instead, but there's exactly the same problem. So, I think, the problem is not in phpMyAdmin but in MySQL, Apache or something. MySQL seems to work if I use command line to access it. Apache & PHP seems to work also, as the login page of phpMyAdmin displays correctly.

• How to circle out something in a picture?

  - by T...

  What is the easiest way to circle out something in a picture, like this example This is accomplished in Gimp: Here are the steps necesary to draw an empty ellipse without clearing the contents of the image below it. 1 - Layer New layer 2 - Make the layer to be the same size as the image and layer fill type to transparency. This should be already selected by default. 3 - On the toolbox select the ellipse select tool and make an ellipse 4 - Use the bucket fill tool to paint the ellipse with your desired color. 5 - Right click on it and go to Select Shrink... 6 - Type in how many pixels you want the border to be and click ok. 7 - Go to the menu and click Edit Clear. I feel it is very indirect, in the sense that first fill out the region enclosed by the ellipse, and then shrink the region to the boundary. I wonder if there is a quicker and more direct way to circle out something, such as by directly drawing the boundary? My OS is Ubuntu. What I was asking may be done outside of gimp, but must be by some software under Ubuntu. Thanks!

• Input/output error reading USB backup drive on CentOS 6.4

  - by Kev

  I'm suddenly seeing some strange behaviour on our USB backup drive that doesn't make sense to me: (2013-10-21 14:58:23 [root@newdc /]$ cd /mnt/backup/ (2013-10-21 14:59:03 [root@newdc backup]$ ls -la ls: reading directory .: Input/output error total 0 (2013-10-21 14:59:05 [root@newdc backup]$ df -h /mnt/backup Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 843G 28G 97% /mnt/backup How is it possible for the OS to know how much is in use, but I can't ls any of it as root? Or more to the point, what problem does this indicate? /var/log/messages said this: Oct 21 14:57:54 g5 kernel: EXT4-fs error (device sda1): ext4_journal_start_sb: Detected aborted journal Oct 21 14:57:54 g5 kernel: EXT4-fs (sda1): Remounting filesystem read-only But...read-only is something different than 'throw an io error'... After unmounting to try fsck on it, I had someone on-site look at it, and the drive was not spun up, and had a slow-flashing light, which I believe means it was in a power-suspend mode. So I had them unplug and replug the USB cable, and now (before remounting) it says: fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) /dev/sda1: clean, 2805106/61046784 files, 181934167/244182016 blocks I then mount it and now ls works and df reports: Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 680G 191G 79% /mnt/backup What would cause it to go into such a state without being asked to? Why all the weird behaviour, and now it appears to not be corrupt?

• Intel HD Graphics vs NVIDIA Quadro FX 380 PCI-E

  - by Michael

  I recently purchased an Acer Veriton which has an i5-650 processor, Windows 7 Pro (64 bit) and Intel HD Graphics listed as the video card. I also purchased a PNY nVIDIA Quadro FX 380 PCI-E card for improved picture and home video viewing and editing. I have already replaced the original 300 wattt power supply to a 430 watt Antec Truepower I had on hand and boosted the RAM to 8 gigs from the original 4. Question 1) Am I getting any improvement in visual quality or system speed with the Quadro or is it a waste of money and I should just save up to buy a bigger video card? This card was on sale for $115. If I am getting improvement then I need to ask another question. Question 2) Instructions for the Quadro installation are as follows... 1--Uninstall the existing VGA driver. -Remove the existing Display Driver via "Add or Remove Porgrams". -Shut down your computer. 2--Remove your Existing Graphics Board (or Disable Integrated 3D Graphics Controller). skipping instructions on how to remove existing graphics board -Systems with integrated (also know as on-board) 3D graphics may require you to disable the integrated 3D graphics system. Consult the owners or vendor manual that came with your PC on how to properly do this. So is the Intel HD Graphics considered a 3D graphics controller? If so should I just contact Acer or can anyone give me instructions? Thanks in advance for any help.

• Platform to allow users to suggest and vote for ideas

  - by Simon

  I head up a support team for a software product. I am in the process of setting up a blog (Wordpress.org), a forum (PHPBB or maybe Vanilla), a means to view bugs (probably expose Jira), but would also like to allow our customers to suggest enhancement requests. Currently we have this as a 'contact form' via the blog, which feeds into a dedicated inbox, which the product manager reviews and may include some of these ideas into the product. However, I would like to give the clients more power/visibility over this. Have a look at ideas.arcgis.com. There are plenty of other similar sites as well. Users can suggest new ideas Other users can vote these ideas up or down (similar to Stack Exchange sites) Ideas that are voted highly will be given a higher priority over lower ones. We can report back on the # of ideas we implement, and potentially reject ideas with reasoning. Has anyone seen any platforms (ideally free) which would replicate something similar to this? I was half thinking of embedding Vanilla within a wordpress page, but need to look into it more.

• DSL Connection drops

  - by user60024

  Ok, I just moved so I had to switch from Cable to DSL. I know very little about computers or internet connections and such, so I had AT&T come out to the new house to set up their highest speed. When they got here, they told me that I needed to downgrade to 3.5mbps because I was too far away. Well we did and everything was going great for two days until I started experiencing random disconnects which have been happening now for about 2 to 3 weeks. I am using a N300 Wireless Dual Band ADSL2+ Modem Router and my ethernet cable is hooked directly into my computer from it. I recently started to notice that it disconnects around 5:30 and 8:30, which may be because a lot of people are on their computers(?) and that it works perfectly fine, almost, all the time if I'm not playing a game. During this time, when I try to load up World of Warcraft the Internet light disappears and the DSL light begins blinking. (So maybe it's too much for the modem and it resets?) Other than that it is amazing, but I'd like to try and fix some of these problems. If you need more information, let me know on how to get it for you and what to do. Thanks for the help!

• Maintenance window and recovery for a large database

  - by NYSystemsAnalyst

  One of our teams is developing a database that will be somewhat large (~500GB) and grow from there (I know 500 Gigs may seem small to many of you, but it will be one of the larger databases in our shop). One of the issues they are grappling with is backing up and restoring the database. Basically, the database will have several "data" tables and one table used for storing images / documents. We need to accomplish the following: Be able to quickly backup and restore only the data tables (sans images) to our test server for debugging and testing purposes. In the event of a catastrophic database failure, restore the data tables only to get most of the application up and running ASAP. Then, restore the images table when possible. Backup the database within the allotted nightly time window (a few hours). My questions are: Is it possible to accomplish the first two goals while still having the images stored in the same database? If so, would we use filegroups, filestream, or something else? How do other shops backup their databases in a reasonable time window while maintaining high availability? Do you replicate to a second server and backup from there?

• Suspected Corrupted Windows 7 MBR?

  - by AridDecay

  So, this may not be the correct place to put up my question, but i'll give it a shot. I'm having an issue repairing this computer. It was brought to me with the described issue of 'Not turning on' Later, I found that it would come with the error of 'No boot sector found on internal hard drive.' I assumed it was an MBR issue due to a virus or cutting a Windows update short. I booted into my trusty recovery enviroment and ran bootrec.exe /FIXMBR and restarted -- No luck I started to think (After multiple attempts to get the MBR sorted out, including creating a new boot sector) that the Hard-drive was possibly starting to cave in on itself, so I booted into a linux bootable CD and went to check the SMART data. Odd, say's it's inaccessible. That seems odd to me, considering it's a newer (two years old or so) Windows 7 computer. All new Hard-drives have SMART. So, I checked the BIOS. No mention of SMART anywhere. Greaaaat. I decided as a last-ditch effort to switch the hard-drive type to ATA in the BIOS (God knows why, I was getting frusterated) instead of AHCI. VOILA! It actually attempts to boot, gets halfway through the little windows animation, does an incredibly (Half a second) quick BSOD, and shuts down. Does anyone have ideas on what's going on here? I'm at my wits end.

• Separate domains vs. one domain with alias-domains

  - by Quasdunk

  I have tried to ask this question a few days ago but I'm afraid it was not clear enough, so here's another try. I have set up a LAMP-server using ISPConfig 3 for the administration. PHP is running over Fast-CGI. I have several domains, like my_site.com, my_site.net and my_site.org, but they all point to the same application/website. Each domain has its own web-root-folder and is running under its own user. The application itself is in a common directory which is owned by another user, like so: # path to my_application (owned by web1) /var/www/clients/client1/web1/web/my_application/ # sym-link to my_application from my_site.com-web-root (owned by web5) /var/www/my_site.com/web -> /var/www/clients/client1/web1/web/ # sym-link to my_application from my_site.net (owned by web4) /var/www/my_site.net/web -> /var/www/clients/client1/web1/web/ With a setup like this I have encountered a few problems concerning the permissions when performing filesystem-operations with PHP. For instance, if the application is called via my_site.com, the user web5 is trying to write something to the application-folder. But the application-folder is owned by the user web1, so web5 is not allowed to write there. As far as I unterstand, this is how Fast-CGI works. After some research and asking a few people, the solution seems to be to break it all down to one domain (e.g. my_site.com) and define the other domains (my_site.org, my_site.net) as alias for this one domain. That way, there would be only one user who has all necessary permissions. However, this would mean that we'd have to buy a multidomain SSL-certificate - but we already have an SSL-certificate for each domain. We were able to use them with our previous provider (managed hosting), and there we also had only one web-directory and multiple domains. So if this was possible, I wonder: Is putting all the domains together into one v-host with one main- and several alias-domains the right approach in this case? Or may I have misunderstood something?

• With puppet, can you have the client ask to be a certain set of roles?

  - by Aitch

  I've recently got my puppetmaster and client up and running and have had the client correctly signed, then requested and applied simple changes, all good. I have a growing number of machines (100). They are not consistently named (historical reasons). They fall into a handful of categories (think of it like: dataserver_type1, dataserver_type2, webserver_type1, webserver_type2....). New instances of these types of machines are added weekly. I don't understand (yet) or cannot see how I can declare a "generic" node of (say) "dataserver_type1" that contains whatever modules it needs, and set something in the client puppet.conf that says "I am a dataserver_type1" without using the hostname/FQDN If I set the node name in the catalog as (say) "my-data-server-type1" - the certified hostname - it picks it up and works. I know you can use patterns for hostnames but as I said, my server names are not consistent, and I can't change them. This seems disingenuous to have to edit a file and manually add a node for each server, when they continue to grow. Edit: Digging deeper, it seems roles may be what I want. But there still seems to be an element whereby the master has contain a list of roles that a specific named server should do. Perhaps what I am asking is, how can a client say "I want to be this role", without the server having to be updated?
